To all rrr/wm t may concer/a Be itlrnown that I, Bonner M. Fnorrrnr,

of Rutherford, Bergen County, New Jersey, f

have invented a certain new and useful Improvement in Smoking Pipes, ofwhich the following is a specification. Y *e v This invention relates to smoking pipes, and contemplates the provision of certain lnovel and improved means for retaining an inner bowl in an outer bowl,zin that particu- To thesev and other usefulends, the invention consists in matters hereinafter set forth and claimed, and shown in 'the accompanyinor drawings in Vwhich: I

n igure 1 is a vertical sectioniof asinolringv A pipe embodying the principles of the invenother form of the invention.

Figure 3 is a similar View showing' Figure l is a similar view showing other form of the invention. j Figure A5 isv a similar View showing another'form of the invention. j

As thus illustrated, and referring to Figure 1, the invention comprises an outer bowl 1 having a well or cavity 2 therein, witha ypassage 3 leading to the stem and mouthpiece of the pipe.v The inner bowl 4 may be of any suitable, known or approved material such as briar wood, or any other suitable wood, or any material which will serve the purpose and permit the formation of screw threads 5 `around the upper portion of this bowl.v vThe outer bowl is provided with similar yscrew threads 6 to engage` the screw threads 5, and with a shoulder I upon which the shoulder -8 of the inner bowl impinges when the inner bowl is screwed .down into place in the outer bowl. The said inner `bowl also has an upper shoulder 9 which engages the top of the outer bowl,'and has a sheet metaly ring or band 10, vwhich covers the top of the inner bowl and extends a distance downwardly inside thereof, as well as a distance downwardly outside to a point below theshoulder 9, sothat the joint between the two bowls is covered. Moreover, this band 10, by extending downwardly outside of the b owl 1, forms a straight'sliding push connection which tends to prevent the threaded upper portion of the outer bowl from splitting or cracking when the'inner bowl is screwed therein.

has a bottom passage 11 to permit the smoke to pass into the chamber 2 in the outer bowl.

In Figure 2 the construction in a general wayris similar to that previously shown and described, but in this case the inner bowl 12 is of clay or some other material, ,andr has a band or ring 13 suitably secured thereto,l the outer portion of which ring is threadedv at 141: toy engage the threaded band 15 which is secured around the upper ortion of the outerbowl 16 of the pipe. j

rior of the upper portion thereof, and the inner bowl has a cork ring 18 which engages this shoulder, thereby providing a straight sliding lpush connectionV between the two bowls, in addition to the rotary screw threaded connection shown and described.

' In Figure`3 the briar wood inner bowl 19 has its upper portion externally threaded at 20{ to engage the screw threads 21 formed internally around the upper portion of the e j M1,542,833 PATENT; OFFICE.

The inner bowl Y aid outer bowl'. v

has a shoulder 17 formedl around the Avinteouter bowl 22, so that the tops of the two n bowls are flush.` The metal band or ring 23 is rigidly secured to the 'inner' bowl, in'any suitable or desired manner, and the outer portion of this ring extends downwardly to vform a straight sliding Apush connection 'with the outer bowl.

In Figure i the inner bowl 24 is of any suitable material, such as clay, and has its upper ring 25 of briar wood or other material which can be screw threaded in a satisfactory manner, as at 26, thereby to engage the screw threads 27 formed internally in the upper end ofthe outer bowl'28, said ring 25 having a shoulder- 29 which engages the top of the outer bowl. A metal band or ring 30 is secured to the inner bowl 24, and to its ring 25, and extends downwardly to a point below the shoulder 29, so that the joint between the two bowls is covered, and whereby a straight sliding pushconnection with portion provided externally with a ies and is :formed with a 'depending annular porti'onwhich isthrea'ded'inside at 33 to engage the screw threads 34: formed externally aroundithe upper portion of' theV outer bowl 35, which latter, like` the others;pre viously shown described, can be of briar or any other suitable, known or approved material. Said outer bowl has an external annular shoulder 36 upon which'the lower edge oi' the annular portion 32 inpinges to 'torni ati'ght joint, and the inner bowl engages the outer bowl atrto torni a straight sliding push connection vbetween the `two bowls, :as shown, in a'dditionfto the'rotary screw "threaded connection, so that 'the threaded upper portion of the outer bowl is `held tightly betweeninner and outer walls which notvonly torni a tight'joint between the two' bowls, but also tend to prevent said threadedportioniiroin splitting or cracking'. A .ietal band orriiia; 38 may be'applied'to the top' of the inncrbowl 3l, inthe in'anner previously described, to extend downward -elow the shoulder. 36 to coter trie external joint bet "een'tlie two bowls.

rlhus in each case both a straight sliding push connection and a rotary threaded screw connection vare provided between the two bowls, with 'a metal ring sealing` and protecting the screw joint between the two bowls in each 'forni ofthe invention, and forming a'handleby which to 'unscrew the inner bow-l, as for example inlFigure'lin -which the band or`ring '10 slides smoothly and tightly upon the outer bowl to'orin the sliding orI push connection, and in which' the two' bowls are screw threaded to provide. the rotary screw threaded connectionbetween them, thus ensuring a tight joint between the twol bowls, with spacebetween the two bowls, tending to reduce heating ofthe outer bowl, obviously, and affording an opportunity for the use of materials which would not bepossible, or which might be inipracticable. ifonly the o-iie Vjoint orftheether were used, instead of bothv otheni. Also, as explained, any external joint orined bevtween the two bowls is covered and screw threaded portions are protected against xlsplitting or cracking, in the manner shown "ineans including a inetal "ring and having provisions toforinzaV rotary sepa 1able screw connection between saidouter-bowl'and said inner bowl, V'sothat thereniovable'bowl is 'supported entirely at'its top portion, said inetal'ring being secured to the top ot the inner bowl and extending-'down outside'o said outer bowl, sealingand protecting.y the screwjOint, `and compelling-rotation oi the ring,l as a handle by which to unscrewf the inner bowl, whereby said inner bowland the ring can only be reinoved togetherfby rotation thereof.

3. A structure,as'specihed in claiin 1,'said rotary connection comprising botha fsinooth push connection andthe screw connection.
